由国家科委主办的第四届北京分析测试学术报告会及展览会于1991年10月在北京举行。该会的宗旨是推动国内外厂商的技术和贸易合作,增进各国科学家的友好往来,促进分析测试学术交流。自1985年首届会议以来,这一会议每两年举行一届,已成惯例。虽然历届会议参加的厂商总数并无增氏,但据承办者公布的材料,国内厂商参展摊位数增加较大。这次会议,有来自13个国家和地区的厂商展出了总价值约2700万美元的分析仪器,包括电子显微镜、质谱仪、光谱仪、色谱仪、电化学仪器及其他各种仪器。
The 4th Academic Conference and Exhibition on Beijing Analytical Testing hosted by the State Science and Technology Commission was held in Beijing in October 1991. Its purpose is to promote technology and trade cooperation between domestic and foreign manufacturers, enhance the friendly exchanges among scientists from all countries and promote the exchange of analytical testing and academic exchanges. Since the first session in 1985, the conference has been held every two years and has become the norm. Although the total number of manufacturers participating in previous meetings did not increase, according to the materials released by the contractors, the number of domestic exhibitors increased considerably. At this conference, vendors from 13 countries and regions exhibited a total of about 27 million US dollars of analytical instruments, including electron microscopes, mass spectrometers, spectrometers, chromatographs, electrochemical instruments and various other instruments.
